| 4.3.2 | Diagramming a standards-based Ethernet cable run from the workstation to the HCC, including distances

In a simple star topology with only one wiring closet, the MDF includes one or more horizontal cross-connect (HCC) patch panels. HCC patch cables are used to connect the Layer 1 horizontal cabling with the Layer 2 LAN switch ports. The uplink port of the LAN switch, depending on the model, which is unlike other ports because it does not cross over, is connected to the Ethernet port of the Layer 3 router using patch cable. At this point, the end host has a complete physical connection to the router port.

You should review the TCS Overview to determine what the user expects for the number of horizontal cable runs to each room that the MDF or IDF will be servicing in its catchment area.
